Hi
This bug seems to partially exist, I tried alpha2 version,
it works fine if the server receives Solicit directly from the client,
however I still get segmentation fault when server receives relay-forward.
Any clue how to get it working?
---- my configuration file ----
ddns-update-style none;
ddns-updates off;
do-forward-updates off;
#Subnet of DHCP Server
subnet6 fe80::/64 {
range6 fc00:0000:4491:0200::/64;
option dhcp6.name-servers fc00::10:zzzz:zzzz:zzzz;
}
---- my configuration file ----
